Recently I tried Cheese Kimbap for the first time, and it is very simple to make at home. All you need to do is make kimchi fried rice, spread it on seaweed, add cheese, roll it into a kimbap, then microwave it until the cheese melts. If you are fast, you can have it ready in 30 minutes.
Heat one tablespoon of oil in a wok over medium heat until shimmering. Add the chopped onions and garlic and cook for 2-3 minutes.
Add the chopped kimchi and cook for another 30 seconds. Add the cooked rice and increase the heat to high. Stir fry for 6-7 minutes. Remove the wok from the heat and stir in toasted sesame oil and salt. Allow the rice to cool for at least 10 minutes before rolling. This will prevent the seaweed from shrinking.
Place a sheet of nori on a bamboo mat. Spread 1 cup of kimchi fried rice over the ¾ of the nori, leaving about 1 ½ inches uncovered on the top side. Add a single line of mozzarella cheese to the center of the rice.
With both hands and a firm grip, gently roll the mat until you reach the other side. Slowly remove the mat as it goes over the top of the kimbap.
Place the kimbap on a plate and microwave for 30-60 seconds to melt the cheese. Remove the kimbap and drizzle it with toasted sesame oil and sesame seeds on top.
Wet a sharp knife with tap water (this prevents the rice from sticking to the knife), then cut the kimbap into bite-sized pieces. Serve immediately.
